Design And Implementation Of Automatic Generation Tool Of Class Library Of Traffic Information Data Element Standard

In the process of software development, the class library plays a very important role, itcan greatly increase the development efficiency of programmers, avoid some simple tediousoperations, allow programmers to focus on other core designs. Through the class library calls,program codes will become concise; program debugging will also become more simple andeffective.Data element standard of traffic information is made into class library, which providesconvenient standard application methods for developers of traffic information system. Butalong with the continuous renewal and expansion of traffic data element standard, theseprevious class libraries can’t meet the need of the application, so, in order to call class librarieswhich are produced by new data element standard, this paper designs a class library automaticgeneration tool, class libraries can be generated in the meantime.With the idea of object-oriented design class library, traffic information data elementstandards are abstracted into data element three layer structure which has inheritedcharacteristics.Paper mainly includes following:Firstly, theory basis and technologyfoundation are described, and they mainly introduce the related concepts of data element threelayer structure; Then, requirement analysis is described, and it points out requirement andfunctional goals of system;Then, the soft design and implementation are carried on, and theyexpound the technical route, give the system function block diagram, use case diagram, classdiagram, at this stage, the various classes of the system are designed, according to the systemdesign document encoding implementation. C#class library, Java class library and C++classlibrary are respectively created; Finally, the software is tested and packaged.Tests show that system can generate the correct class libraries, can meet the demand asregard the call of software developers, and also has a positive effect for standardization oftraffic information. The system has met the expected requirements on the project.
